Setup
Initial Charging
Before first use, fully charge your Monoprice BT-300ANC headphones. Connect the provided USB-C charging cable to the headphone's charging port and the other end to a USB power source. A full charge takes up to 3 hours. The LED indicator will show charging status.
Power On/Off

Operating Instructions

The headphones support Bluetooth Version 4.0 and have a range of up to 32 feet (10 meters).
Active Noise Cancellation (ANC)
